The mechanism that loads ~/.Xdefaults into the X server resource database is 
nicely obscure, so I'm not sure that -q actually avoids that.

The definitive way to check would be to move ~/.Xdefaults aside, restart the X 
server then start emacs (I'm not sure if your clean install test would have 
done this or not)

Another thing which might be worth trying is to see if the behaviour changes 
in a non-UTF-8 locale, e.g. export LANG=C and then run emacs.

So far it seems that (1) emacs takes a long time to start up (2) xterm starts 
up quickly.  Are there other X applications that you use and how do they behave?
